Jennifer Aniston and Lisa Kudrow have already said it, but leave it to Courteney Cox to make things crystal clear.

There won't be a "Friends" reunion, no matter how many '80s and '90s shows hop on the bandwagon.

"It's not gonna happen," Cox said on David Letterman's "The Late Show" on Monday.

The actress says she can't even get the cast together for a meal.

"I've been trying to put together a cast dinner for 10 years. It doesn't happen. I can get the girls to come, maybe Matthew Perry. Matt Le Blanc canceled last time right at the last minute, Schwimmer lives here (in New York)," Cox said. "So it's not gonna happen."

Besides, she points out, "Friends" was a pretty limited comedy.

"We did the whole show on a soundstage in Monica's apartment, pretty much," Cox laughed. "So what are we gonna do?"
